Understanding the underground fraud economy - dark web markets, criminal tools, and how fraud operations are organized
Criminal Infrastructure — The Market Behind the Attacks
Last updated: 2025-08-26 · Estimated time: 10–14 min
Modern fraud runs on a supply chain: markets, tools, operators, and cash‑out routes. Know the stack and you’ll know where to break it.
The BidenCash Playbook (Real Case)
Story (true): In 2022, a carding market called BidenCash opened shop. To win buyers, it gave away huge “free dumps” of stolen cards—public stunts that drove traffic. The site worked like a business: seller onboarding, listings, support, and fees. In June 2025, U.S. authorities seized about 145 domains linked to the operation. The message was clear: this is organized commerce, not random chaos.

The Stack (How It Fits Together)
- Markets (the storefront): discovery, reputation, escrow, “support,” and affiliates.
- Vendors (the suppliers): stolen cards/creds, fullz, access, tools.
- Tool makers (the tech): checkers, autobuy bots, proxy services, fake‑ID kits, OTP bypass/bot frameworks.
- Operators (the workforce): cash‑out crews, social engineers, SIM‑swappers, mules.
- Cash‑out (the exit): drops, reshipping, mixers, prepaid rails, high‑risk MIDs.
Defensive moves
- Treat it like a supply chain: disrupt inputs, platforms, and outputs.
- Share signals with issuers/networks; many patterns are cross‑merchant.
- Expect publicity‑driven surges after big “free dump” events.
